Study Questions Whether Stents Relieve Chest Pain

A new medical study questions whether the hundreds of thousands of Americans with clogged heart arteries who choose to implant stents to relieve chest pain will actually feel any benefits. The study, recently published by The Lancet, found that while the mesh wire did improve blood flow, patients were still hurting. Dr. Ajay Kirtane, director of Cardiac Catheterization Laboratories at Columbia University Medical Center, joins Hari Sreenivasan to talk about its implications.
